Preparation method of novel superfine tailing cemented filling slurry
A preparation method of novel superfine tailing cemented filling slurry belongs to the technical field of mine filling and is characterized in that superfine tailings are made into balls, and the tailings balls, the superfine tailings, cementing powder and water are uniformly mixed and stirred through a stirring system and then are conveyed to a goaf through a mine filling system; the superfine tailings and the cementing powder are put into a disc of a mining pelletizer in proportion, the mining pelletizer is started to enable the disc to rotate continuously, water is evenly sprayed to the outermost surface of the mixed dry material in the disc through a spraying system, the mixed dry material is changed into spherical particles from particles under the action of capillary force and extrusion force, and the spherical particles are dried. The tailing balls have certain strength after being maintained in a normal-temperature maintenance workshop; and the tailing ball clusters with certain strength, the superfine tailings, the cementing powder and the water are uniformly stirred through a stirring system to prepare the filling slurry. According to the method, all the mine superfine tailings can be utilized, the cost of a cementing material is saved, the strength of a filling body is enhanced, the mine production safety is guaranteed, the economic benefits of enterprises are improved, and the technical implementation cost is low.
一种新型超细尾砂胶结充填料浆制备方法，属于矿山充填技术领域，其特征在于：本发明将超细尾砂盘制成球，尾矿球与超细尾砂、胶固粉和水通过搅拌系统均匀混拌后，利用矿山充填系统输送至采空区；按比例将超细尾砂与胶固粉放入矿用造粒机圆盘中，启动矿用造粒机使得圆盘持续转动，水分通过喷淋系统均匀喷洒于圆盘中混合干料最表面，混合干料在毛细管力和挤压力作用下由微粒变为球状颗粒，尾矿球经常温养护车间养护具有一定强度；一定强度的尾矿球集群与超细尾砂、胶固粉和水通过搅拌系统均匀搅拌制成充填料浆。本发明可实现矿山超细尾砂全部利用，节约胶凝材料成本，增强充填体强度，保障矿山生产安全，提高企业经济效益，技术实现成本低。
